Abstract: 593,113. Gauging-apparatus. IMPERIAL CHEMICAL INDUSTRIES, Ltd. (Remington Arms Co., Inc.). June 8, 1945, No. 14524. [Class 106 (ii)] Gauging apparatus for gauging the height of articles such as ammunition primer cups, comprises a rotatable hopper unit consisting of a flat base plate 43 with a true upper surface, and one or more annular walls 52, 53 accurately spaced a predetermined distance from this surface, each wall having a downwardly disposed flat gauge surface, the space between the upwardly and downwardly disposed surfaces constituting a gauging gap, and the inner edge-portion of the annular surface being bevelled so that its height above the base plate decreases outwardly toward the gauging gap. The annular walls 52, 53 are secured to the base plate 43 by screws 57 through lugs 54, being spaced therefrom by members 58 to provide gaps representing maximum tolerance for the inner and minimum tolerance for the outer walls respectively. The sloping base plate 43, which is rotatable about a spindle 14, is engaged by a friction wheel 38 driven by an electric motor 31 mounted' on a slide and pulled by a spring 35 to maintain the necessary pressure for the friction drive. The cylindrical primer cups which are to be gauged for height are placed in the central hopper space within the annular wall 52 and those not higher than the maximum tolerance tend to slide through the gauging gap between the base plate and the lower edge of the annular wall during the rotation, while those too high are caught in the gap by virtue of a slight bevel 61a, Fig.10, on the lower edge of the wall 52 and are carried round to the top where a cam finger 89 guides them into a tube 77 through which they pass into a receptacle. In a similar manner, the the primer cups of correct height are carried round by the outer wall 53 and scooped into a tube 78, while the undersized cups pass through the second gauging gap into a stationary hopper 20 and then out through a spout 24. In the embodiment described, two hopper units are mounted side by side within a common hopper 20, the base plates being rotated in opposite directions by a common motor. The friction drive wheels are adjustable along their shafts to give different speeds. Spacer members 58 and-cam fingers 89 can be changed for gauging articles of different sizes.
